I use a place called BBRepair.com and have sent Blackberries to be repaired by them with data on it. They have called me and asked what I wanted done with the data. I told them to wipe it. You could send your Blackberry off to them to get repaired or at least see how much it would cost to get it repaired. They might even be able to wipe the data for you so you can send it back to Verizon.
